Making Props for SF Movies

[ManiacallyChallenged]

I think the question was what kind of futuristic weapon you would make. As in: were you to make a sci-fi movie, what would your ideal future guns look like?

I'd be cool with anything, as long as they didn't try to pass the Calico series off as laser rifles. Maybe I would build something off the Glock 17, since it seems like it would be easy to add a shell to. I actually like the look of that one .22 Select Fire pistol that was made to replace the .45 1911 but failed at it(surprise. Can't replace the 1911.)

Two things also bug me.
1: Shiny laser guns.
2: Really scratched up laser guns.
Both seem like they are far too extreme. Who issues their troopers with guns with the finish 80% off? The Rebels sure, but nobody else in their right mind.
